2. Asking the big energy questions:
How do we live sustainably on our planet?
What tradeoffs must be considered if our society gets serious about making the transition from a consumptive society to a sustainable society?

3. A proposition:
We NEED energy. The FORM of energy and the FUELS we use to create convenient energy are a matter of choice.
(Electricity for buildings/Vehicles)

4. Write with your neighbor!
Fossil Fuels  Sustainable Energy
What tradeoffs must be considered if our society gets serious about making the transition from a consumptive society to a sustainable society?

5. So what will take the place of fossil fuels?

6. Every power system has pros and cons

7. Solar power must be stored for nights and cloudy days

8. Are we asking the wrong question?
Should we be looking for a one-to-one substitution solution?

9. Distributed power vs centralized power
Creating a paradigm shift

10. Current electricity grid
One major regional power plant, usually coal, natural gas or nuclear supplies area’s needs
Same plan throughout US

11. Our electric “grid” = power plants connected to consumers

12. Our electric “grid” = power plants connected to consumers

13. A new energy concept
Distributed Power = dispersed, small-scale power systems customized to geographic region combine to meet a region’s needs

14. The mix that works for Houston would be different than the mix for Detroit.

15. A Smarter grid – (how is it smarter? Compare to centralized)

16. Smart grid and smart meters
Information allows for smart decision making
Expected connectivity with major appliances

17. Decentralized power Advantages Disadvantages
Greater reliance on renewables
Decreased climate change
Protection from centralized power outtages (storms, malfunction, terrorism)
New jobs/new industries
Promote more community
Disadvantages
Change is difficult
Need for new infrastructure which may be costly
Requires more cooperation
Some jobs will be lost
Shift in local economies

18. Sooooo . . . . . how would YOU put it all together?
Fossil fuels  climate change
Demand for electricity and transportation
Tradeoffs of all energy sources
Growing population and affluence
I=PAT

19. Home Energy Audit -
Create a plan to reduce your electrical use at home.
